Embedded Clips

Open Flash by clicking on the Flash Icon on the dock:
Create a new document. Make sure it is Actionscript 2
Save (+SHIFT+S) document in work folder Save as embedded_clips:
Create at least three layers
- Actions
- Buttons
- Images
In Frame 1 of the Image layer create your background image
Create an object either by inserting a new movie clip or creating a new layer and drawing on that layer. When Drawing is complete, select the image and convert to a movie clip (F8)
In Scene 1, name your movie clip
Open the library and doube click on your movie clip to open it
Add more layers and elements
On one layer create an element that will be invisible-convert it to a movie clip, name the instance in the properties window
Return to scene 1
Click on frame 1 of button layer and add a button (Windows>Other Panels>Common Libraries>Buttons)
Name the instance of the button in the properties window
Click on frame 1 of the Actions layer and open the actionscript window

Create functions that control at least one property of your embedded clip when an event occurs.
From previous example:

btnName.onPress = function() {
    movie_clip.moveclip_obj._visible = 0;
};
btnName.onRelease = function() {
     movie_clip.moveclip_obj._visible = 1;
};
btnName.onReleaseOutside = function() {
    movie_clip.moveclip_obj._visible = 1;
};

Save, play and publish your movie, then link to and from homepage.

Here's an example of what you could try (but remember to embed your movie clip in another movie clip):

stop();
snd = new Sound();
snd.attachSound("Bubbles.aif");

_root.tank.fish1._visible = 0;
_root.tank.bubbles._visible = 0;
_root.tank.fish1.dx = -2;
_root.tank.fish2.dx = -2;
for (x=1; x<=2; x++) {
    _root.tank["fish"+x].onEnterFrame = function() {
        this._x += this.dx;
        if (this._x<(_root.tank._x-(_root.tank._width/2+this._width/3))) {
            this._x = (_root.tank._x-_root.tank._width/2)+this._width/2;
            this.dx *= -1;
            this._xscale *= -1;
        }
        if (this._x>_root.tank._x+this._width) {
            this._x = _root.tank._x+this._width/2;
            this.dx *= -1;
            this._xscale *= -1;
        }
    };
    _root.tank["fish"+x].onRollOver = function() {
        snd.start(0,1);
        _root.tank.bubbles._visible = 1;
        _root.tank.bubbles._y = this._y+_root.tank.bubbles._height/2;
        _root.tank.bubbles._x = this._x;
        _root.tank.bubbles.onEnterFrame = function() {
            if (this._y>=_root.tank._y+_root.tank._height/3) {
                this._y -= 3;
            } else {
                this._visible = 0;
            }
        };
        
    };
}
_root.btn.onRelease = function() {
    if (_root.tank.fish1._visible == 0) {
        _root.tank.fish1._visible = 1;
    } else {
        _root.tank.fish1._visible = 0;
    }
};
